Chapter 1 可数与不可数名词及其使用

可数与不可数的分野

可数名词： 有清晰的边界且可被视为独立体

If a noun can be counted, it will have a clear boundary (physically or conceptually) and will be seen as a separate entity.

• There were several managers present at the meeting.
• A few more models were developed to try to resolve this issue.

不可数名词： 无边界或极限

An uncountable noun means no boundary or limit can be formed for it; that is why these nouns are commonly qualities, feelings, and social processes.

• There was confusion because the government had previously acknowledged that
  the problem was not a financial one.
